b18a vs b18b...which is better? what are the differences? are there any pros/cons of either one?

thanks

 

identical bottom end/CR

hp/tq difference is in the head and cams

 

the b18a in most cases will be cheaper due to its age so its a good bet for a rebuild. the newer b18b has a better flowing head although it is nothing very special. the 2 will also differ in terms of OBD.

try searching. good luck

 

i currently have a 93 ls/vtec with a b18a bottom end and i was considering buying a block but its a b18b....

so having a difference in the ODB would mean an adapter for my current ecu correct?

 

both Weak Sauce B20

 

i would tend to agree. after almost 2yrs with my LS now, i wish i had bought a b20b.

no, you can use both a b18a or b18b, it will require no difference in electronics
